Explicitly state supported Linux versions
Add META tags Linux-Maximum and Linux-Minimum. One pain point for package maintainers is ensuring the compatibility of the packaged version of ZFS with the Linux kernel. By providing an authoritative compatibility guide in the source tree, maintainers can automate compatibility checks. Additionally, increase META string extraction specificity. configure.ac finds Name and Version by a very simple `grep`, which might conceivably find other fields. Require the string be at the beginning of a line, and be followed by a colon to avoid such confusions.
